The invention relates to thermoplastic moulding materials containing A) between 20 and 97 wt. % of a thermoplastic polyester; B) between 1 and 40 wt. % of a phosphinic acid salt and/or a diphosphinic acid salt and/or the polymers thereof, constituent B) having an average particle size (value d50) which is smaller than 10 µm; C) between 1 and 30 wt. % of a nitrogenated flameproofing agent; D) between 0 and 5 wt. % of at least one ester or amide of saturated or unsaturated aliphatic carboxylic acids having between 10 and 40 C atoms and aliphatic saturated alcohols or amines having between 2 and 40 C atoms; and E) between 0 and 60 wt. % of other additives. The total weight percent of constituents A) to E) amounts to 100 %.
L'invention concerne des matières moulables thermoplastiques contenant A) 20 à 97 % en poids d'un polyester thermoplastique ; B) 1 à 40 % en poids d'un sel d'acide phosphinique et/ou d'un sel d'acide di-phosphinique et/ou de leurs polymères, sachant que la composante B) a une granulométrie moyenne (valeur d¿50?) inférieure à 10 µm, C) 1 à 30 % en poids d'un agent ignifuge azoté, D) 0 à 5 % en poids au moins d'un ester ou amide d'acides carboxiliques aliphatiques saturés ou non saturés ayant 10 à 40 atomes de carbone et d'amines ou alcools aliphatiques saturés ayant 2 à 40 atomes de carbone, E) 0 à 60 % en poids d'autres adjuvants. Le total des pourcentages des composantes A) à E) étant égal à 100 %.
